my, Dan, and Mike are competing in a cooking competition. They all used different amounts of milk from a container holding 6 gallons of milk.

Amy used 13% of the total milk in the container.
Dan used 0.14 of the total milk in the container.
Mike used 0.5 gallon of the total milk in the container.
Who used the greatest amount of milk from the container? Show your work and explain your answer in words.

Answer 1

8

Explanation:

First, Fiona had 18 dollars, so Fiona spent 4.25, which would give her 13.75, but she needed to save 9.75, so 13.75-9. 75 = 4 dollars. So, Fiona would buy crackers, so the crackers would cost 50c, so how much will 50 give you 4 dollars? It will be 8, so the answer would be 8.

Answer 2

1.
`18-4,25=13,75 \\ 13,75-9,75=4 \\ 0,50x \leq 4` ⇔
`x= (4)/(0,50)`⇔
`x= 8`
R: She can buy 8 crackers

2. Amy used 13%
Dan used 0,14*100 = 14%
Mike used 0,5*100 = 50%
R: Mike used the greatest amount of milk.
